Yes, you may.
However, the first JCL commands implies that these are tape, or removable,
datasets, and that there is a desire to keep the same tape (volume)
mounted. Using the second form will lead to a dismount of the volume which
contains DATA.FILE.ONE and the operator mounting of the volume which
contains DATA.SET.TWO
There is a reason for using UNIT=AFF=INFILE :-)
